Method Details

tryToReach

boolean tryToReach(@NonNull Iterable<V> startVertices,
 @NonNull Predicate<V> goalPredicate,
 int maxDepth,
 @NonNull C zero,
 @NonNull C costLimit,
 @NonNull Function<V,Iterable<V>> nextVerticesFunction,
 @NonNull BiFunction<V,V,C> costFunction,
 @NonNull BiFunction<C,C,C> sumFunction,
 @NonNull AddToSet<V> visited)

Search engine method.

Parameters:

startVertices - the set of start vertices

goalPredicate - the goal predicate

maxDepth - the maximal depth (inclusive) of the search Must be >= 0.

zero - the zero cost value

costLimit - the algorithm-specific cost limit

nextVerticesFunction - the next nodes function

costFunction - the cost function

sumFunction - the sum function for adding two cost values

visited - the visited function

Returns:

true on success
